Darn that doctor for saying that. This disease isn't
too bad for lots of people, in fact, it can be quite mild. The person that said that is probably stuck in the early 1980's or so when treatments and research were limited. You
really can control the course of the disease to some extent by following a healthly lifestyle with diet, exercise and stress reduction.
Enjoy that baby

and stick around if you have more questions or need support.
